'VENTILATFL Application ied December 10, 1925. Serial No. 74,440.

@ur invention relates to improvements in ventilators for vehicle bodies.

The object is to provide a ventilator for a vehicle body which is soconstructed that either the front end or the rear end of the ventilatormay be raised to regulate the air admitted through the ventilatoropening into the vehicle body in the manner desired.

y. An important advantage is the provision of a. ventilator ina suitablewall portion of a vehicle body, such as the cowl or roof ofy a closedautomobile, boat or aeroplane body,

which ventilator is so built and has a closure so mounted that eitherthe front end or the 5 rear end of the lclosure may be tilted upwardlyand supported at different elevations in the open position. l

An important advantage of this invention is the fact that ventilation ofthe car body may be had with a strong draft by opening ventilator towardthe front, also ventilation of the car body may be had without any draftby opening ventilator toward the rear.

A. meritorious feature resides-in the conn struction of such aventilator with a minimum number of parts adapted to be easily andquickly operated and held against rattle at any adjusted open positionand which is provided with side wall portions adapted to close theventilator opening'on the sides at any open position of the ventilator.

The vabove objects and advantages, t0- gether with others of importanceand merit, will more fully appear from the following specification,appended ciaims and accompanying drawings, in which:

In Figs. 1 to 10 inclusive of the drawings we have/shown our inventionas embodied in a ventilator mounted in the cowl of an autobile body toventilate the foot space and the interior of the body. In Figs. 11 to 13we haveshown an embodiment of our invention disposed in a wall portionsuch as the roof of a vehicle. Obviously our ventilator may be installedat any suitable place in the wall of the body of the vehicle. Inautomobile practice ventilators are commonly placed either in the cowlor roof of closed bodies.

itis ldesirable that a ventilator be capable of regulation so that theair draft Iaxllmitted through 4the ventilator opening may Ibe controlledto meet the requirement-s and the con dition of the weather. At one timea strong air blast maybe needed while at another t-ime the minimumamount of air movement may be required. Our ventilator is of such a.char acter as to meet these requirements and varimum and minimum amountof air iiow. Through the use of our invention ventilation may beaccomplished with or without creating a draft. i f

In Figs. 1 to 10, let 20 indicate the cowl of an automobile bodyprovided withfan instrument board 22 and a dash board 2. The cowl isprovided with ajventilator open` ing having a coaming 26 about itsmargin. A closure 28 isprovided for such opening. This closure hasv adownwardly-extending flange adapted to seat over the coamin 26, Theclosure is provided with side wal ous intermediate stages between themaxilos portions 31 arcuate in form which extend ownwardly within theopening on opposite sides and serve to close the opening at .the sidesat any position ofelevation,

The closure is so supported that either the front end or'the rear endmay be elevated. to an open position and mechanism is provided toelevate either the front end or the rear end of the closure and tosupport sides at both the frontv and rear end. These pivot pins areremovably received in notches 34 formed in the coaming 26 so that eitherthe front or the rear end of the closure may be raised, the closurepivoting about the pivot pins at its opposite end.

To elevate the closure we provide an operating member 36 which extendsthrough the instrument board and. is. provided interiorly of the bodywith a handle 38' and is supported at the opposite end in the dash*l 24for'endwise movement. A link 40 is piv- 'oted at 42 .to the rear en`d ofthe lclosure and is provided with a saddle 44 slidably mounted upon'therod 36. A link 46 is pivoted at 48 to the forward end of the closure andis provided with a saddle 50 slidably mounted upon the rod' 36. lStops52 are carried by the rod 36, being-positioned beyond the saddles 44 and5 0. -An expansion coil spring 54 vis carried by the rod 36 interposedbetween the saddle members 44 and 50 tohold them n art, as appears inFig. 1, so as to hold the c osure in the covered position.

'It will be seen that when the operating rod 36 is moved forwardly tothe position shown in Fig. 2, the rear end ot the closure will be tiltedupwardly. It the operating rod 36 is moved rearwardly beyond thepositionshown in Fig. 1, the forward end of the closure would be tiltedupwardly. The closure would in each instance pivot about its pivotalconnection at the opposite end from the elevated end. The rod 36\, isprovided With a plurality of notches 56 adapted to engage over the edgeof the opening 58 in the instrument board through winch the rod passesto hold the sameat adjusted positions.

In Figs. 4, 5 and 6 we have illustrated a modified form of our inventionin which we employ the pivot pins 32-described in con-v nection with thedescription of Figs. 1 to 3 and the notches 34 in the coaming alsohereabove described 'o servevas pivotal mountings for each end of theclosure. To raise and lower the closure we provide different operatingmechanism. A pair of brackets 60 are secured to the wall portion of thebody, as appears in Figs. 4 and `5, and a spring 62 engagesthesebrackets with the adjacent side wall portions'31 ofthe closure,exerting aA downward pull on the closure vto hold it thereof and as thelever is moved in the opposite direction the closure will be rocked totilt .the rearward end upwardly. This o en position is shown in dotted'outline in ig. 4 and in full outline in Fig. 5,. l

In Figs. 7 ,to 10 we have shown a second modified form of operatingmechanism. A link 70 is pivoted at 72 to one side of the closure at oneend. A corresponding link (not shown in the drawing) is pivoted to thesame end of the closure at the opposite side. Opposite ends of ,theselinks are pivoted at 74 to the roaming. The closure is provided at theend opposite that to which the link is pivoted with a saddle 76 adaptedto seat over a pivot pin mounted in the eoaming. An arm 78 extendsdownwardly from the closure and is pivoted at its lower end to anoperating rod 30. v This operating rod is provided with notches 82 andextends through an instrument board and is adapted to be adjustablymoved through the opening therein in the same manner as described inconnection with 'the operating rod shown in Figs. 1 to 3.

Anti-rattling springs 84 are'wound about los i the pivot pins 74 andengaged at one end over the link 70 and at the opposite en against theside wall of the body, whilesimilar anti-rattling springs 86 are woundabout the pivot'pins 72 and engaged at one end against the closure andat the opposite end againstthe link 70. It will be seen that as theoperating member 8O is moved forwardly the forward end of the closure iselevated while if it is moved rearwardly the closure is rocked toelevate the rearward' end. v

Iax Figs. 11 to 13 we have shown a third modilied form of our invention,here illusf trated and used in the roof of a vehicle body. The rooforother side wall portion is 'in V- cated as 88 having a ventilatoropening surrounded by a coaming 90 and a closure 28 provided with amarginal flange 30 and side walls 310i the'same character as describedin connection with the construction shown in the figures heretoforeexplained.

JA rotatable cam 92 is pivoted by a. pin 94 to the coaming 90. Thispcamis eccentrically mounted in a side wall portion 31 of the Handles 100are secured to the under side oi" the closure at each end and when theclosure has been raised t0 the position shown in solid line in Fig.11either one of these handles may be grasped and either end lof theclosure pulleddown upon the coaming so as to elevat-eeit-her the frontor the'rear end of the closure, the adjusting nuts 96'be'ing loosenedand tightened to permit the completion of these operations.

What we claim is:

- 1. In a road vehicle body, -a wall portion provided with a ventilatoropening having a surrounding coaming, a closure for said openingprovided with a marginal iange adapted to seat over said coaming, a pairof hnks one on each side ot the openlng, each link pivoted at one endtherein. and at the opposite end to the closure whereby, the closure maybe swung upwardly withsaid links about their pivot or swung upwardlyaway from the links about its pivotal connection therewith, an armdepending below said closure and an operating lever engaging said arm toswing the same to tilt the closure upwardly from either end,` a springabout the pivot at one end of the link engaging the link and theadjacent side of the opening and a spring about the pivot at theopposite end of the link, engaging the link and the closure.

2. In a road vehicle body, a wall portion provided with a ventilatoropening having a surrounding coaming, a closure for said openingprovided with a marginal ange adapted to seat over said coaming, a

air of links one on each Vside ot the openingpivoted atv one endtherein, each of. said links pivoted .to the opposite end of the closurewhereby -such end of the .closure may be swung upwardly thereby, whilethe opposite and free end of the closure may be swung upwardly, theclosure pivoting about its connection with said links, saddie members onthe opposite and free end of `the.closure adapted to engage over pivotswithin the opening when the opposite end of the closure is swungupwardly, an arm depending below the closure substantially intermediateits ends, a lever pivoted to said arm'to swing the same in one directionto tilt one end of the closure upwardly and to swing the same in theopposite direction to tilt the opposite endfof the closurev upwardly.

In testimonywhereof, we sign this specification.
